If the freezing point of a `0.01` molal aqueous solution of a cobalt (III) chloride-ammonia complex (which behaves as a strong electrolyte) is `-0.0558^(@)C`, the number of chloride (s) in the coordination sphere of the complex if `[K_(f)` of water `=1.86 K kg mol^(-1)]`

Answer» Correct Answer - 1
`DeltaT_(f) = iK_(f)m`
`0.0558 = ixx 1.86 xx 0.01 rArr i=3`
Structure should be: `[Co(NH_(3))_(5)CI] Ci_(2)`
